[SOLVED] led lights won't turn on

[finn crawford]

Phanteks 5v led strip connected to Addressable LED Header, motherboard b450 elite, won't turn on, using fusion 2.0
not sure if the header is 5v or 12

See your mobo manual p. 15. You have two D_LED headers - one on bottom edge to rear of middle, one on top right - with 3 pins in a (4-1) layout. For each right next to it is the DLED_VSW jumper set. Set each of those to the 5 V setting. The 12 V option is for an uncommon older design that required that voltage.

Both headers were already set to 5v, tried the top-right header but still isn't working, I think the problem is with fusion 2.0? or they might be broken

Do you have any friends with mobos with an ARGB header that is working with some ARGB lights? Could you temporarily take your Phanteks lights to their place and connect to test the light strips?

tried it on my brothers pc, worked instantly, plugged into ARGB header

Good. So we know the light string works. But in your machine it still does not? Have you tried it on the other D_LED header just in case? If it won't work on either header, maybe try Un-installing MSI Mystic Light, reboot, and re-Install to see if that helps.

I had two LED strips daisy-chained together, which wasn't working, so I tried plugging one stip in and it worked, so I thought two 5v strips would need a 10v header, both of my strips are now broken
thank you for trying to help.

Good job on that tactic, perhaps trying on multiple would indeed help in knowing if the header might be the problem or reveal potentially more issues to resolve.
